Answer:
-10
Step-by-step explanation:
The greatest common factor (GCF) of the expressions is a product of the GCF of the numerical coefficients and the variables. The GCF of the 24 and 80 is 8. Additionally, the GCF of x^4 and x^5 if x^4. Thus, the GCF is 8x^4. The answer to this problem is letter C.
<h2>A is the correct answer!</h2><h3></h3><h3>x: -7 <u>+ 2</u> = -5</h3><h3>y: -12 <u>+ 4</u> = -8</h3><h3></h3><h3>x: -5 <u>+ 2</u> = -3</h3><h3>y: -8 <u>+ 4 </u>= -4</h3><h3></h3><h3>That is enough information to get an answer.</h3><h3></h3><h3><em>Please let me know if I am wrong.</em></h3><h3 />
C because the square root of 8 is 64
Start by looking at the vertex form of a quadratic function, f(x) = a(x - h)^2 + k. The variables h and k are the values of the vertex. Plug those in to get f(x) = a(x - 4)^2 + 5. To find the variable a, plug in the point given for the x and y values. So, you get (21) = a((8) - 4)^2 + 5. Solve for a algebraically, and you get a = 1. Finally, plug everything in and simplify the equation. You should get that the quadratic function is f(x) = x^2 - 8x + 21. Hope this helps!
